It started out as a joke in an Amsterdam art gallery in 2003, but has since flourished into a fully-fledged sporting event. A simple concept really – play four minutes of chess followed by two minutes of boxing. The one who reigns victorious does so either by knockout or checkmate. Plus don’t forget about the legendary after-party DJs and special guest cabaret. It’s a night jam-packed with a punch (pun very much intended). Bonus: Free drink for any chessboxing banners or fancy dress, claim at the box office. Ringside seats. Over 18s only. After-party in bar until 3am.
